No. For me to even consider favoring characters as potential waifu and husbando material, I must believe that I can put up with them. Although I like watching both characters on-screen, I firmly believe that, if I were to interact with them one-on-one, I'd eventually snap and punch them in the face. Multiple times.

Wait. Is the question whether I'd consider a romantic relationship with someone like Haruhi Suzumiya, or is it whether I think Lelouch and Haruhi should hook up? The answer to the former is a tentative yes, the latter a resounding no.
